VALVE Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed. October 17, 1906. Serial No. 339,402.

To all whom it may concern:

Be it known that I, FRANK W. KLINE, a citizen of the United States,residing at North Germantown, in the county of Columbia and State of NewYork, have invented new and useful Improvements in Valves, of which thefollowing is a specification.

This invention relates to valves of the rotary type, designed especiallyfor use in controlling the steam inlet and exhaust of engine cylinders,and has for its objects to provide a comparatively simple, inexpensivedevice of this character which may be readily operated, one which inaction will be ground to its seat, thus insuring a constantly effectivejoint for preventing leakage, and one which may be adjusted forregulating the amount of steam admitted to and exhausted from thecylinder to govern the speed of the engine.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings: Figure 1 is a side elevation of an enginecylinder equipped with a valve mechanism embodying the invention. Fig. 2is a horizontal section taken centrally and longitudinally through thecylinder. Fig. 3 is a detail, sectional view taken on the line 3-3 ofFig. 2.

Referring to the drawings, 1 designates an engine cylinder having at oneend a stuffing box 2 through which is extended a piston rod 3 providedwith a piston head 4 arranged for reciprocation Within the cylinder,these parts, which are conventionally shown herein, being of the usualor any appropriate construction and material and adapted in practice toperform their ordinary functions.

Formed on one side of the cylinder 1 is a valve casing 5 having aremovable face plate 6 and provided with an internal valve chamber 7,preferably of trunco-conical form, as shown, there being connected withthe casing and for communication with the chamber 7 through the mediumof a port 8 a main steam supply pipe 9 and a main exhaust pipe 10 whichcommunicates with the chamber through the medium of a port 11, whilecommunicating at their outer ends with the cylinder 1 and at pointsadjacent the ends of the latter is a pair of oppositely extended branchinlet pipes or ducts 12 having communication at their inner ends withthe chamber 7 through passages 13 and a pair of branch exhaust pipes orducts 14 commmunieating with the valve chamber through passages 15.

Fitted in the chamber 7 is a rotary truncoconical valve 16 provided witha central, outwardly projecting stem 17 on which is fixed a crank arm 18provided with a longitudinal slot 19 in which is adjustably ar ranged acrank pin 20 through the medium of which the arm 18 is connected with anoperating rod 21 in turn connected in the usual manner with the engineeccentric for operating the valve in the usual manner, there beingformed at opposite points in the periphery of the valve a pair ofchannels or depressions 22, 23, constituting passages for connecting theinlet and exhaust pipes during the operation of the device and in themanner more fully hereinafter explained.

In practice, supposing the valve 16 to be in the position illustrated inFig. 3, the inner end of the port 8 and one of the ports 13 will beconnected for communication through the medium of the passage 22, thusadmitting steam from the supply pipe 9 through the left-hand pipe 12 tothe cylinder for imparting an outstroke to the piston, the port 11 beingat the same time connected for communication with the right-hand port 16through the medium of the passage 23, thus to establish communicationbetween the exhaust pipe 10 and appropriate branch pipe 14 forpermitting steam to exhaust from the cylinder during the outstroke ofthe piston. At the completion of the outward movement of the piston, therod 21 will be actuated for partly rotating the valve, through themedium of the crank arm 18, to establish communication between the inletpipe 9 and other branch pipe 12 and between the exhaust pipe 10 andleft-hand branch pipe 14, as illustrated by dotted lines in Fig. 3,whereby steam is admitted to the cylinder for effecting instroke of thepiston and permitting the proper exhaust of the steam during suchstroke.

It is to be particularly observed that in operation the valve will beconstantly ground on its seat for maintaining a steam tight jointbetween the parts, and further, that by adjusting the crank pin 20 backand forth longitudinally of the slot 19 the degree of movement of thevalve may be varied to con trol the amount of steam admitted to thecylinder and consequently govern the speed of the engine. Also it is tobe noted that the crank arm 18 may be manually operated for properlymanipulating the valve in the operation of starting or stopping theengine, and further that by adjusting the valve to an intermediateposition for cutting off communication between pipe 9 and both of thepipes 12, at which time communication between the pipe 10 and both ofthe pipes 14: will be closed, the operation of the engine will be fullystopped.

Having thus fully described my invention, what I claim is: I

l The combination of a cylinder having in its cylindrical wall a pair ofinlet and outlet ports adjacent each end, a casing at one side of thecylinder and disposedbetween the ends thereof, said casing open at oneside and having a frusto-conical chamber and threaded openings in thewalls of the chamber and arranged in pairs at opposite sides of thecasing, a frusto-conical valve in the chamber provided with arcuateports in its surface, a stem on the valve, a plate having an aperturefor receiving the stem, fastenings for securing the plate to the valvecasing for closing the open side thereof, means for oscillating thevalve,tubular conduits independent of the casing and cylinder and havingthreaded engagement in the said openings and ports and located outsidethe casing and cylinder, a supply pipe connected with the casing tocommunicate with one of said valve ports, and an exhaust pipe connectedwith the casing to communicate with the other of said valve ports.

2. The combination of a cylinder having a pair of spaced inlet andoutlet ports in its side adjacent each end and each pair being arrangedapproximately the same distance from the end of the cylinder, avalvecasing formed integral with the cylinder and projecting outwardlytherefrom and having a chamber, the axis of which is disposed at rightangles to that of the latter, said casing being provided with oppositelydisposed live steam inlet and exhaust steam outlet openings and alsowith a pair of openings at opposite sides of the casing, supply andexhaust pipes having threaded engagement in the in let and outletopenings, a pipe between each opening of the casing and one of saidcylinder ports, the pipes being'composed of separate parts havingthreaded engagement in the ports and side openings, couplings connectingthe parts of each pipe together, an oscillatory valve in the casingarranged with its axis at right angles to the axis of the cylinder andprovided with ports arranged to connect the inlet and exhaust openingsof the casing with the side openings of the latter, a plate bolted tothe casing for covering the chamber thereof and retaining the valve inposition, and means for oscillating the valve.

3. In an apparatus of the class described, the combination of a cylinderhaving a laterally extending valve casing and a pair of threadedopenings adjacent each end, and arranged in the sametransverse plane,oppositely disposed inlet and outlet steam pipes connected with thecasing, a pair of supply and exhaust ducts extending from each side ofthe casing and engaging in the threaded openings of the cylinder, afrusto conical valve mounted in the casing for rocking movement andprovided with peripheral ports one arranged to connect the inlet pipewith one of the supply ducts connected with the forward end of thecylinder while the other connects the exhaust duct leading from the rearend of the cylinder to communicate with the outlet pipe, a plate securedto the casing for holding the valve therein and having an opening, apacking between the plate and easing, bolts extending through the plateand screwing into the casing, a stem on the valve passing through theopening in the plate in a direction at right angles to the axis of thecylinder, an arm on the stem for rocking the latter, and an adjustablereciprocating member connected with the arm.

In testimony whereof, I afiix my signature in presence of two witnesses.
